Conserving  Moisture  with  the  Disk  Harrow 

The  disk  harrow,  properly  used,  will  do  more  to  increase  the  crop  yield  than  any  other  farm  implement 
It  lends  itself  to  a  variety  of  uses.  When  used  directly  after  the  binder,  it  forms  a  dirt  mulch  which  protects 
the  moisture  in  the  sub-soil  from  the  evaporating  heat  of  the  sun.  The  farmer  who  takes  this  precaution  to 
preserve  moisture  is  invariably  repaid  by  the  heavy  crop  he  harvests  the  following  year. 

The  use  of  the  disk  harrow  immediately  before  the  plow  produces  results  that  the  farmer  cannot  afford  to 
neglect.  A  seed  bed  may  to  all  appearances  be  in  ideal  condition  to  produce  a  large  crop,  while  in  reality  it 
is  not  even  well  enough  prepared  to  return  the  cost  of  producing  the  crop.  This  condition  of  the  soil  is  usually 
found  where  the  land  is  not  disked  before  plowing.  Sod  or  stubble  ground  will  often  break  into  large  lumps 
as  it  is  turned  to  the  bottom  of  the  furrow.  The  lumps  thus  left  form  lartje  air  spaces  which  break  up  capillary 
attraction  and  prevent  the  proper  amount  of  moisture  from  reaching  the  plant  roots.  By  using  the  disk  harrow 
before  the  plow,  the  stubble  or  sod  is  thoroughly  broken  up,  so  that  when  turned  to  the  bottom  of  the  furrow 
it  is  in  a  mellow  form  which  readily  absorbs  moisture  and  furnishes  nourishment  to  the  plant  roots.  Used  at 
the  proper  season,  the  disk  harrow  will  effectively  destroy  obnoxious  weeds  —  another  manner  in  which  moisture 
is  preserved  for  the  use  of  the  growing  crop, 

The  results  obtained  by  the  use  of  the  disk  harrow  depend  largely  upon  the  time  that  the  disk  is  used. 
The  ground  should  be  disked  as  soon  as  possible  after  it  has  taken  in  moisture.  No  time  should  be  lost  after 
the  soil  is  sufficiently  dry  for  the  disks  to  scour.  The  great  advantage  of  disking  when  the  soil  is  in  this  condi- 
tion is  that  all  the  moisture  is  stored  in  the  sub-soil  for  future  use,  and  the  surface  is  formed  into  a  granular 
mulch  which  will  not  blow  away.  Old  ground  can  be  disked  while  in  this  condition  with  the  same  satisfactory 
results  found  when  the  disk  harrow  is  used  on  sod.

The  McCormick  disk  harrow  with  forecarriace.     Fore- 
carriage  is  supplied  on  special  order  at  additional  cost 

The  McCormick  disk  harrow  is  one  of  the  strongest  harrows  made.     It  has  a  reputation  for  doing  the  best 

work  under  all  conditions  and  standing  up  under  the 
work  for  years.  The  great  strength  of  the  main  frame 
arid  the  manner  in  which  it  is  fastened  to  the  bearings 
account  for  the  good  work  of  this  harrow  and  the  depth 
to  which  the  gangs  penetrate  the  ground. 

The  draw  frame  of  the  McCormick  disk  harrow  is  made 

of  one  piece  bar  steel  reinforced  where  the  greatest  strain 

comes.     The  cross  sill  is  angle  steel.     Two  pole  angles 

made  of  steel  are  riveted  solidly  to   the    center    of   the 

cross  sill  and  draw  frame,  making  the  strongest  and 

at  the  same  time  the  lightest  frame  known. 

The  steel  angle  bars  take  the  place  of  the  stub 
pole  when  the  regular  pole  is  set  to  one  side  for 
three  or  five  horses.  This  gives  great  strength  and 
rigidity  of  the  frame.  The  draw  frame 
is  fastened  to  the  bearing  standard  by 
means  of  eye-bolts,  which  gives  ab- 
solute freedom  of  motion  to  the  gangs. 
As  a  result,  the  frame  does  not  in  any 
manner  interfere  with  the  action  of 
the  disk  when  set  at  cutting  angles. 
For  this  reason  the  McCormick  disk 
harrow  penetrates  the  ground  as  deep 
as  the  user  desires.

Strong  Gang  Frame 


It  is  of  just  as  much  im- 
portance to  have  a  strong 
gang  frame  as  it  is  to  have 
a  rigid  main  frame  on  the 
disk  harrow.  The  main 
frame  holds  the  gangs  level, 
but  the  good  vi'ork  of  the 
scrapers  and  disks  depends 
upon  the  strength  of  the 
gang  frame.  The  gang 
frame  of  the  McCormick  disk 
harrow  is  made  of  two  angle 
steel  bars  solidly  fastened 
together  with  steel  bars  at 
the  end.  The  bearing  stand- 
ards are  solidly  fastened  to 
the  angle  bars.  This  con- 
struction holds  the  bearings 
in  a  line  with  the  axle,  so 
that  there  is  no  possible 
chance  for  them  to  cut  out 
by  twists  and  strains. 
The  spools  between  the  disks  are  made  with  wide  flanges,  giving  the  disks  extra  support.  The  holes 
in  the  disks  and  spools  are  square  and  fit  the  arbor  bolt  closely.  It  is  utterly  impossible  for  a  disk  to  turn  in 
the  arbor  bolt  even  though  it  should  become  loose.  The  arbor  bolt  is  fastened  with  a  lock  nut  so  that  it  will 
not  loosen. 


A  strong  gang  frame  is  necessary  for  good  disking 


Level  Gangs 


It  is  a  well-known  fact  that  a  disk  harrow  will  not  do  its  best  work  unless  the  gangs  are  working  level. 
When  a  farmer  disks,  he  wants  to 
level  the  ground  as  well  as  cultivate 
it.  If  a  harrow  gang  follows  the 
unevenness  of  the  ground,  the  best 
disking  is  not  being  done. 

The  gang  on  the  McCormick  disk 
harrow  can  always  be  kept  working 
level,  whether  the  harrow  is  new  or 
whether  it  has  been  used  a  long 
time.  An  adjustable  snubbing  block 
takes  up  any  looseness  or  wear  that 
may  take  place,  and  the  curved  set 
lever  bars  keep  the  gangs  level  at 
whatever  angle  they  may  be  set. 
The  curve  in  the  lever  bars  is  so 
made  that  it  takes  care  of  the  circu- 
lar movement  at  the  lower  end  of  the 
set  levers.  The  accompanying  illus- 
tration shows  that  it  is  impossible  for 
the  McCormick  disk  harrow  to  buckle 
in  the  center  when  the  snubbing 
block  is  properly  adjusted.

Efficient  for  Work  on  Side  Hills 


Each  gang  on  (he  McCormick  disk  harrow 
is  controlled  by  a  separate  lever.  These  levers 
are  within  convenient  reach  of  the  driver  and 
are  easily  operated.  Much  better  work  can 
be  done  with  the  disk  harrow  when  each  gang 
is  operated  by  a  separate  lever.  One  of  the 
great  advantages  of  the  two-lever  construction 
on  the  McCormick  harrow  is  its  efficiency  for 
work  on  side  hills.  When  working  on  very 
steep  side  hills,  there  is  always  a  tendency 
for  disk  harrows  to  work  down  the  hill.  By 
setting  the  gang  on  the  lower  side  at  a  greater 
angle  than  the  one  on  the  upper  side,  the 
harrow  will  retain  its  natural  position,  which 
is  not  possible  unless  the  gangs  can  be  set  at 
uneven  angles. 

If  the  gangs  are  set  at  different  angles, 
dead  furrows  can  be  filled  or  ridges  removed 
from  the  ground. 

Center  Tooth 

It  frequently  happens  that  a  farmer  has 
occasion  to  disk  the  ground  but  once.  When 
doing  this  with  the  ordinary  disk  harrow, 
there  is  a  ridge  left  between  the  gangs.  The  McCormick  disk  harrow  is  equipped  with  a  center  tooth,  which 
cultivates  and  levels  this  ridge  between  the  gangs.  Every  portion  of  the  ground  is  cultivated  when  the 
McCormick  disk  harrow  is  used.  By  means  of  a  lever  and  quadrant,  the  center  tooth  can  be  adjusted  for  deep 
or  shallow  cultivation,  or  raised  high  from  the  ground  when  transporting  the  harrow.  The  lever  and  quadrant 
for  raising  and  lowering  the  center  tooth  is  placed  in  front  of  the  seat,  within  convenient  reach  of  the  driver. 


The  gangs  can  be  set  at  different  angles  for  side-hill  cultivation

Scrapers 


The  scrapers  used  on  the  McCormick  disk 
harrow  are  of  the  steel  rocking  type.  Each 
scraper  is  independent  of  the  other,  and  can 
be  removed  or  adjusted  separately.  When 
in  its  regular  position,  the  scraper  is  near  the 
center  of  the  disk  and  does  not  rub.  By 
means  of  a  foot  lever,  they  can  be  moved 
from  the  center  toward  the  edge  of  the  disk, 
so  that  no  matter  what  condition  the  soil  is  in, 
the  disks  are  always  kept  clean.  The  coil 
spring  attached  to  the  scraper  bar  can  be 
adjusted  to  give  any  tension  to  the  scraper 
that  the  operator  desires.  The  tension  can  be 
changed  instantly  without  the  use  of  any  tooL 


The  tension  of  the  spring  in  the  scraper  bar  can  be  changed  insteuitly  without

Construction  of  the  Disk 

The  disks  for  the  McCormick  disk  harrow 
are  made  of  a  high  quality  of  steel,  ground 
and  polished  so  that  dirt  does  not  adhere  to 
them.  They  are  the  right  shape  for  good 
work.  They  are  flat  enough  to  penetrate  the 
ground,  and  yet  have  sufficient  curve  to  pul- 
verize it  thoroughly.  Anyone  can  satisfy  him- 
self of  this  fact  by  watching  the  work  of  the 
McCormick  disk  harrow  in  the  field. 


oizes 

The  McCormick  disk  harrow  is  furnished 
with  8,  10,  12,  14,  and  16  disks.  The  disks 
are  made  16,  18,  and  20  inches  in  diameter. 
When  working  in  extremely  hard  ground,  the 
small  disk  is  preferable  ;  in  loose  sandy  soil, 
the  large  disk  will  be  found  to  give  the  best 
satisfaction.

Durable  Bearings 


The  bearings  used  on  the  McCor- 
mick  disk  harrow  are  the  most  dur- 
able ever  devised  for  this  kind  of 
an  implement.  If  kept  well  supplied 
with  oil  they  will  never  -wear  out. 
They  are  provided  virith  a  large  cen- 
ter ring  projection  to  relieve  the 
ends  of  the  bearings  of  end  thrust. 
This  eliminates  extra  draft  and  wear. 
The  bearings  are  chilled,  have  a 
large  wearing  surface  which  makes 
them  very  durable.  Dust  bands  fit 
over  the  ends  of  the  bearings  to 
prevent  dirt  from  falling  in.  These 
bearings  are  as  nearly  dust  proof  as 
it  is  possible  to  make  them.  No  one 
ever  heard  of  the  McCormick  disk 
harrow  bearings  vi^earing  out  if  they 
received  the  proper  amount  of  oil  at 
all  times.

Easy  to  Oil 


The  oiling  arrangement  on  the  McCormick  disk  harrow  is  conveniently  placed  so  that  the  operator 
can  oil  the  harrow  v^^llen  standing  behind  it.  This  eliminates  the  danger  that  comes  from  standing  in  front  of 
a  harrow  when  horses  are  hitched  to  it.  Another  advantage  of  the  convenient  oiling  arrangement  is  that 
the  more  easily  a  man  can  get  at  his  machine  to  oil  it  the  better  care  and  attention  he  will  give  it.  The  oil 
pipes  in  the  McCormick  disk  harrow  are  easily  cleaned.     These  pipes  are  large,  and  oil  flows  into  the  large 

groove  which  encircles  the  center  of  the  bearing.     This  causes  the  oil 

to  be  fed  evenly  to  all  parts  of  the  bearing.  This  uniform  film  of  lubri- 
cant keeps  the  bearing  from  wearing  and  makes  the  McCormick  disk 
harrow    an    exceptionally   easy   running    and    long-wearing  implement.

McCormick  Disk  Harrow  Forecarriage 

A  forecarriage  will  be  furnished  with  any 
McCormick  disk  harrow  on  special  order  at  addi- 
tional cost.  It  is  of  special  use  in  working  close  to 
fences,  in  preventing  the  tongue  from  lashing  the 
sides  of  the  horses,  and  in  keeping  the  harrow 
running  steadily.  The  bearings  are  fitted  with  hard 
oilers.  Dust  cannot  get  into  the  bearings  if  suffi- 
cient grease  is  used  so  that  it  oozes  out  at  the  collar. 
The  McCormick  forecarriage  can  be  used  with 
or  without  a  pole.  It  requires  only  a  few  seconds 
to  change  the  pole  from  the  center  to  one  side,  or 
to  remove  it  entirely.  The  pole  can  be  set  either 
to  the  left  or  the  right-hand  side,  enabling  the  farmer 
to  adjust  the  pole  to  his  team. 

The  McCormick  forecarriage  can  be  raised  or 
lowered  to  five  different  positions.     This  makes  it 
possible  to  fit  the  forecarriage  to  any  size  team  and 
still  have   the   line  of   draft   such    that    the    fore- 
carriage  wheels  will  just  touch   the  ground.     This   keeps   the 

harrow  working  in  a  line  without  adding   to  the  draft  of  the 

implement. 

The  regular  pole  of  the  McCormick  disk  harrow  is  bored 

to  fit  the  forecarriage.     It  is  only  necessary  to  order  the  set-over 

irons  for  use  with  3  or  5  horses,  or  the  pole  plates  when  using 

2  or  4  horses.     This  eliminates  the  necessity  of  buying  an  extra 

pole  for  this  attachment.     When  ordering  a  harrow  with  the 

forecarriage,  care  should  be  taken  to  state  whether  the  pole  is       McCormick  forecarriage

McCormick  cutaway  disk  harrow   with  forecarriage 


The  principal  dilTerence  between  the  McCormick  cutaway  disk  harrow  and  the  regular  disk  harrow  is  that 
the  cutaway  is  equipped  with  cutaway  disks  and  a  special  type  of  scraper.  The  work  done  by  the  cutaway  is 
very  similar  to  that  of  a  regular  harrow,  except  that  the  cutaway  stirs  the  ground  in  larger  chunks  and  does  not 
pulverize  it  as  finely  as  the  regular  harrow.  The  cutaway  disk  harrow  is  furnished  in  the  same  sizes  as  the 
regular  harrow. 


Transport   Trucks 

Both  the  McCormick  regular 
and  the  McCormick  cutaway 
disk  harrows  can  be  equipped 
with  transport  trucks.  These 
trucks  are  of  particular  value 
when  moving  from  one  field  to 
another.  It  takes  only  a  little 
of  the  driver's  time  to  apply  or 
remove  them.  They  are  fur- 
nished on  special  order  at  a 
slight  additional  cost.

Tandem  Attachment  for  McCormick 
Disk  Harrow 


McCormick  tandem 
attachment 


It  is  a  well-known  fact  that  the  best  results  are  secured  with  the  disk  harrow  when  the  ground  is  double 
disked  or  gone  over  twice  in  opposite  directions.  To  do  this  with  the  ordinary  disk  harrow  takes  up  a  great 
deal  of  time  that  is  not  always  to  be  had  at  the  planting  season. 

The  McCormick  double  disk  harrow  consists  of  the  regular  McCormick  disk  harrow  with  an  inthrow 
cutaway  harrow  attached  as  a  trailer.  It  is  a  practical  machine  for  the  man  who  wishes  to  double  disk  and 
whose  time  to  do  so  is  limited.  The  action  of  the  disks  on  the  tandem  attachment  is  just  the  reverse  of 
that  on  the  regular  harrow.     As  a  result,  the  soil  is  well  pulverized  and  a  good  seed  bed  is  formed. 

The  taffdem  attachment  is  equipped  with  the  same  bearings  and  conveniences  for  oiling  which  are  used 
on  the  regular  McCormick  disk  harrow.  It  is  equipped  with  a  lever  on  each  gang,  so  that  the  gangs  can  be  set 
at  different  angles  for  side-hill  cultivating.  The  gangs  are  kept  working  level  by  means  of  steel  straps  in  the 
center.  Steel  scrapers  keep  the  disks  clean  in  all  conditions  of  soil.  These  scrapers  are  furnished  on  special 
order  at  slight  additional  cost. 

The  tandem  attachment  on  the  McCormick  double  disk  harrow  is  made  in  4,  5,  6,  7  and  8-foot  sizes.

McCormick  Peg -Tooth  Harrow 

A  peg-tooth  harrow  is  subjected  to  a  great  many  hard  knocks.  It  is 
often  necessary  to  use  it  in  rocky  soil  or  where  there  are  many  tough 
roots.  This  means  that  a  harrow  to  do  this  work  must  withstand  a  great 
many  twisting  strains.  The  ordinary  peg-tooth  harrow  will  not  stand 
this  kind  of  work  for  any  length  of  time. 

The  McCormick  peg-tooth  harrow  is  unusually  strong  for  its  weight. 
This  is  due  to  two  strengthening  bars  on  each  section,  which  make  it 
impossible  for  a  tooth  to  catch  on  a  stone  or  other  obstruction  and  bend 
the  bar  to  which  it  is  attached  without  bending  every  other  bar  in  that 

section.  The  tooth  beams  are  U- 
bars,  thicker  in  the  center  than 
at  the  edges  —  a  construction 
which  makes  them  unusually  light 
and  strong. 

The  tooth  clips  are  forged 
from  steel  and  are  fastened  with 
two  nuts,  making  a  very  sub- 
stantial fastening.  The  teeth  have 
up-set  heads  and  are  of  steel, 
tempered  to  give  good  cutting 
edges.  They  can  be  furnished 
/j-inch  square  or  ^8-inch 
diamond  shaped.  The  diamond- 
shaped  tooth  gives  exceptionally 
long  wearing  service  and  the 
peculiar  shape  keeps  the  teeth 
sharpened  for  easy  draft. 

The  McCormick  peg-tooth 
harrow  is  furnished  with  20,  25, 
30,  and  35  teeth  to  a 
section.  Each  section  is 
attached  to  the  drawbar, 
making  the  harrow  very 
flexible. 


A  harrow  equipped  with  this  strengthen* 

ing  bar  will  not  bend  even  under  the 

weight  of  a  heavy  man 


This  is  what  happens  to  a  harrow  not  equip* 

ped  with  strengthening  bars  when  it 

strikes  an  obstruction

Slip  Ratchet  Easily  Operated 


The  McCormick  peg-tooth  harrow  is  equipped  with  a  shp  ratchet  with  fine  notches,  which  permit  close 
adjustment  of  the  teeth.     A  slip  ratchet  is  a  great  advantage  when  a  number  of  sections  are  in  use.     The  teeth 

have  a  wide  range  of  adjustment, 
and  are  so  placed  on  the  harrow 
that  trailing  is  impossible.  Each 
tooth  must  do  its  full  share  of  the 
work. 

The  McCormick  peg-tooth  harrow 
is  equipped  with  a  runner  tooth  at 
each  corner  of  the  sections.  This 
makes  it  possible  to  transport  the 
harrow  from  one  field  to  the  other 
without  tearing   up  the  ground.

Orchard  Guards 

When  harrowing  among  trees,  vineyards,  and  where  the  outer  ends  of  the  tooth  bars  are  apt  to  come  in 
contact  with  posts,  vines,  stumps,  etc.,  the  orchard  guards  serve  as  a  protection.  These  orchard  guards  also 
prevent  trash  from  catching  on  the  ends  of  the  tooth  bars.  They  are  furnished  only  on  special  order  at  a  slight 
additional  cost. 


Riding  Attachment 


The  McCormick  riding  attachment  is  composed  of  two  long  arms,  which  fasten  to  the  drawbar  of  the 
harrow,  and  an  axle  so  made  that  the  wheels  turn  in  when  turning  corners.  This  enables  the  driver  to  make 
short  turns  without  the  wheels  sliding  or  tipping  up.  The  wheels  are  made  of  steel  with  staggered  spokes  and 
are  high  enough  to  keep  the  driver  well  out  of  the  dust.  They  have  wide  tires  so  they  will  not  pack  the  ground. 
This  attachment  is  always  in  line  with  the  draft  and  does  not  disturb  the  good  work  of  the  harrow.  It  can  be 
furnished  with  any  peg-tooth  harrow  at  a  slight  additional  cost. 


The  riding  attachment  is  connected  to  the  drawbar,  and  does  not  affect  the  Hood

The  17-tooth  harrow  cuts  5  feet,  4  inches. 
The  23-tooth  harrow  cuts  7  feet,  3  inches. 
The  25-toofh  harrow  cuts  8  feet.

15,  17,  23,  or  25  teeth 


Soil    must  be  properly 
aerated    to    bring    out    the 
best  plant   growth.     If  air 
does  not  circulate  through 
it  readily,  it  becomes  sour 
and    will   not    develop    its 
greatestsupplyof  plantfood. 
There  is  no  implement  that 
so  thoroughly  airs  the  soil 
as  the  spring-tooth  harrow. 
For  this  reason  it 
has   an  important 
place  in  the  prep- 
aration of  the  seed 
bed,  and  no  farm 
should  be  without 
its    use.    In   cold, 
damp,     backward 
seasons,  it  is  valu- 
able   for    stirring 
the  ground  so  that 
the    sun    and    air 
can  warm  the  soil 
foranearly  seeding. 

There  are  many 

soil  conditions  in  which  the  spring-tooth  harrow  should  be  used  in  connection  with  a  disk  harrow.     It  is  efficient 
in  loosening  up  fine,  tenacious  soil,  for  killing  weeds  in  the  germinating  period,  and  for  many  similar  uses. 

The  McCormick  spring-tooth  harrow  is  constructed  entirely  of  steel.  The  frame  is  bent  upward  in  front 
and  the  inside  of  each  section  of  the  frame  is  cut  away,  so  that  trash  will  not  accumulate.  The  tooth  beams 
are  high  and  the  teeth  have  sufficient  space  between  them  for  the  trash  to  work  its  way  through  readily.  The 
teeth  are  spaced  so  that  they  do  not  trail.  They  are  made  of  a  high  quality  of  spring  steel  and  are  fastened  to 
the  tooth  bars  by  adjustable  clamps,  permitting  the  teeth  to  be  adjusted  to  compensate  for  wear. 

Collings  Teeth  for  Cultivating  Alfalfa 

Collings  spring  teeth  can  be  furnished  for  use  on  the  McCormick  spring-tooth  harrow  at  slightly  greater  cost 
than  the  regular  spring  teeth.  These  teeth  are  placed  on  the  McCormick  harrow  exactly  the  same  as  the  regular 
teeth,  the  only  difference  being  the  shape  of  the  tooth  point. 

By  purchasing  a  set  of  Collings  teeth  a  farmer  can  have  an  alfalfa 
cultivator  and  a  regular  spring-tooth  harrow  in  one  implement. 

The  advantage  of  the  Collings  tooth  is  that  it  is  somewhat  stiffer  at 
the  point,  and  does  not  spring  the  full  length  of  the  tooth  when  working 
in  hard  ground. 

A  harrow  equipped  with  these  teeth  does  practically  the  work  of  a 
cultivator.  At  the  same  time  the  tooth  has  a  different  action  in  the 
ground  from  a  stiff-tooth  cultivator.  It  has  the  advantage  of  a  spring 
in  the  tooth  and  is  oval  shaped,  permitting  it  to  pass  the  crown  of  the 
alfalfa  without  doing  it  any  harm.     It  wears  to  a  sharp  point  and,  being 

oval,  does  not  catch  trash  at  the 
end.  This  type  of  alfalfa  cultivator 
loosens  the  surface  of  the  ground, 
giving  the  alfalfa  roots  an  abun- 
dance of  air. 


Runner  shoes  protect  frame  from  wear 


The    Collings  tooth  has  the  same 

adjustable  tooth  fastening  as  the 

regular  tooth.     As  the  tooth  wears 

it  can  be  adjusted

Close  Adjustment  of  the  Teeth 


No  farm  should  be  without  the  use  of  a  sprinR-tooth  harrow 

are  fitted  with  detachable  runner  shoes.     These  shoes  can   be  renewed  when  they 
the  McCormick  harrow  an  exceptionally  long  wearing  frame. 


The  adjustment  of  the 
teeth  on  the  McCormick 
spring-tooth  harrow  is  very 
fine,  so  that  the  operator 
can  cultivate  to  any  depth 
he  desires.  The  sections 
are  hinged  together,  per- 
mitting them  to  follow  un- 
even ground. 

The  draft  hook  is  adjust- 
able, so  that  more  or  less 
weight  can  be  put  on  the 
front  or  rear  of  the  harrow, 
as  conditions  require.  It  is 
usually  desirable,  when 
harrowing  trashy  ground,  to 
have  the  rear  teeth  deeper 
than  the  front,  and  when 
working  in  hard  ground,  to 
have  the  front  teeth  working 
deeper  than  the  rear.  Ad- 
justments to  bring  about 
these  results  can  be  quickly 
made  on  the  McCormick 
spring-tooth  harrow. 

The  bottoms  of  the  frame 
become  worn.     This  gives  , 


McCormick  Vineyard  Spring-Tooth  Harrow 


The  McCormick  vineyard  spring- 
tooth  harrow  can  be  used  for  the 
same  purposes  as  the  regular  spring- 
toolh  harrow.  It  has  the  same 
features  of  construction.  The  prin- 
cipal difference  being  that  it  is 
furnished  in  small  sizes  and  can  be 
equipped  with  guiding  handles, 
which  makes  it  possible  to  use  it  in 
orchards,  vineyards  and  in  crops 
that  are  planted  in  rows. 

Work  can  be  done  with  it  in  many 
places  where  the  ordinary  spring- 
tooth  harrow  cannot  be  used  to 
advantage.  It  is  furnished  with  7, 
9,  and  12  teeth.  The  7-tooth  har- 
row cuts  1  foot,  11  inches;  the  9- 
tooth,  2  feet,  6  inches;  the  12-tooth, 
3  feet,  5  inches.

McCormick  Sulky  Spring -Tooth  Harrow 


The    McCormick    sulky    spring-tooth    harrow 
is  exactly  the  same  as  the  regular  spring-tooth 
harrow,  except  that  a  riding  attachment  has  been 
added  and   the  posi- 
tion   of    the    levers 
changed  so  that  they 
can  be  reached  from 
the  driver's  seat. 

The  sulky  attach- 
ments are  made  in  two 
sizes.  The  17  and 
23-tooth  harrow  takes 
a  slightly  larger  size 
than    the    15-tooth. 

When  ordering  the 
sulky  attachment, 
care  should  be  taken 
to  designate  the  size 
of  harrow  for  which 
it  is  to  be  used. 

The  sulky  attach- 
ment is  so  made  that 
the  entire  weight  of 
the  driver  can  be  put 
on  the  harrow  for 
hard    ground,  or  the 

weight  of  the  driver  can  be  placed  on  the  sulky  wheels  when  working  on  so^t  ground  when  it  is  not  desired  to 
have  the  teeth  penetrate  so  deeply.  The  wheels  are  placed  within  the  frame  of  the  harrow,  where  they  do  not 
trail  on  the  newly  cultivated  ground.

McCormick  Combination  Harrow

^^^^^i^^^a^^ 


The  McCormick  combination  harrow  does  the  work  of  a  spring-tooth  and  a  peg-tooth  harrow  in  one  operation 


The  McCormick  combination  harrow  is  practically  a  spring-tooth  and  a  peg-tooth  harrow  in  one.  The 
trailing  teeth  follow  along  in  the  rear  of  the  spring  teeth,  smoothing  and  leveling  the  ground  and  breaking  up 
the  clods  while  they  are  soft.  This  makes  the  combination  harrow  a  particularly  desirable  implement  for  use 
when  a  farmer  must  prepare  his  seed  bed  hurriedly.  The  McCormick  combination  harrow  has  all  the  advan- 
tages of  the  regular  McCormick  spring-tooth  harrow  and,  in  addition,  has  the  advantage  of  smoothing  the  ground 
at  the  same  time.  The  frames  on  the  McCormick  combination  harrow  are  high  and  pass  over  trash  readily. 
The  teeth  are  spaced  so  that  trailing  is  impossible.  More  or  less  slant  can  be  put  on  the  trailing  teeth  in  the 
rear,  as  conditions  require.  ■  m  The  McCormick  combi-

McCormick  14-Tooth  Cultivator 


The  teeth   on   the 

14-tooth  cultivator 

are  adjustable 


McCormick  14-tooth  cultivator  with  straight  bar  frame 


The  McCormick   14-tooth  cultivator  is  designed    for    deep, 
level  cultivation.    It  is  adapted  to  the  use  of  truck  gardeners,  fruit 
growers,  and  those  who  need  a  tool  for  deep  stirring  of  the  ground 
without  hilling.     The  teeth  are  diamond  shaped  with  a  small 
point  forged  on  the  end.     It  can  be  adjust- 
ed to  cultivate  at  different  depths  and  at 
different   angles,  so  that  very  close  work 
can  be  done. 

The  cultivator  is  furnished  with  or 
without  a  wheel  jack.  The  depth  of  cul- 
tivation can  be  regulated  with  the  wheel 
jack  and  the  clevis  hitch.  The  expanding 
lever  is  a  double  locking  device  which 
makes  the  cultivator  exceedingly  rigid, 
whether  the  frame  is  expanded  or  closed. 
The  teeth  in  the  quadrant  are  very  fine, 
permitting  close  adjustment.  This  enables 
the  opeiator  to  cultivate  as  near  as  he 
desires  to  plants  in  rows  of  unequal  width. 

The  McCormick  14-tooth  cultivator 
is  furnished  with  straight  or  zigzag  bar 
frame  with  expansion  screw  or 
expanding  lever.  On  special 
order  and  at  a  slight  additional 
cost,  this  cultivator  will  be 
equipped  with  double-pointed 
teeth,  giving  the  advantage  of 
reversing  the  teeth  end  for  end 
when  one  end  becomes  worn. 
Teeth  for  destroying  thistles  and 
weeds  with  thick  stalks  will  be 
furnished  on  special  order.

McCormick  Combination  Cultivators 


McCormick  cultivator  No,  51 


McCormick  combination  cultivators  are  made  for 
all  purposes  where  a  one-horse  cultivator  is  re- 
quired. It  is  not  necessary  that  the  rows  be  of 
uniform  width.  These  cultivators  can  be  quickly 
adjusted  for  wide  or  narrow  cultivation.  They  are 
equipped  with  all  the  attachments  necessary  to 
cultivate  all  kinds  of  crops.  They  are  made  in 
three  types,  5,  7,  or  9-shovel.  Nos.  51,  52,  53,  54, 
and  55  comprise  the  5-shovel  series:  Nos.  71,  72, 
7.>,  74,  and  75,  the  7-shovel  type;  Nos.  91,  92,  93, 
94,  95,  the  9-shovel  type. 

The  frames  of  all  these  harrows  are  made  the 
same,  consequently,  by  purchasing  various  attach- 
ments, the  7  and  9-shovel  type  can  be  made  from 
the  5-shovel  type,  thus  the  farmer  can  have  a  culti- 
vator for  all  purposes,  enabling  him  to  do  the  best 
cultivating  under  all  conditions. 


McCormick  cultivator  No.  53 


Shovels 

The  shovels  on  the  McCormick  combination  cul- 
tivator are  reversible,  affording  two  cutting  edge? 
They  are  thicker  in  the  center  than  on  the  edge,  so 
that  they  retain  their  original  shape  until  complete- 
ly worn  out.  The  frame  on  the  McCormick  culti- 
vator is  made  of  bar  steel,  and  is  fastened  in  such 
a  manner  that  it  presents  the  shovel  as  squarely  as 
possible  to  the  ground,  whether  the  harrow  is 
expanded  or  closed.  The  hole  through  the  shovel 
is  square,  and  the  metal  is  raised  on  the  back  so 
that  there  is  very  little  chance  of  the  shovels  ever 
working  loose. 

Moldboards 


The  moldboards  are  arranged  similar  to  the 
moldboard  and  point  of  a  plow.  They  are  reversi- 
ble, the  same  as  the  shovels.  When  one  point 
becomes  worn  the  other  can  be  used.  They  can  be 
adjusted  to  throw  dirt  toward  or  away  from  the 
plants.     They  can  also  be  used  for  hilling.

Works  as  Close  to  the   Plants 
as  Desired 

The  wheel  jack  is  exceptionally  strong  and  is 
made  so  that  the  teeth  can  be  regulated  by  it  as 
well  as  by  the  clevis  hook.  The  clevis  locks  so  that 
it  is  impossible  for  the  singletree  to  come  out  when 
the  horse  backs. 

The  lever  wheel  jack  used  in  connection  with  the 
expansion  lever  on  cultivators  Nos.  55,  75,  and  95, 
makes  it  impossible  for  the  operator  to  c.ulti-vate 
between  rows  of  different  widths,  without  stopping 
the  horse  to  make  adjustments.  This  makes  these 
cultivators  of  exceptional  value  to  the  truck  grower. 

The  improved  lever  expanding  device  used  on 
the  McConnick  cultivator  holds  the  cultivator  frame 
exceptionally  rigid,  whether  closed  or  expanded. 
The  teeth  are  so  spaced  that  close  adjustments  can 
be  made  when  the  cultivator  is  in  operation.  This 
is  of  particular  value,  because  it  gives  the  operator 
an  opportunity  to  adjust  his  cultivation  with  vary- 
ing widths  of  rows,  and  get  as  close  to  the  plants  as 
he  desires.
